Los Angeles ADU Permit Help: Garage Conversions & Backyard Homes

ADUs (accessory dwelling units) and garage conversions are one of the most popular projects in Los Angeles—but the permitting can feel overwhelming. Between state ADU laws, local zoning rules, and separate building, electrical, mechanical, and plumbing permits, many homeowners and contractors get stuck.

Who Handles ADU Permits in LA?

Your permit path depends on where the property sits:

• Inside the City of LA: ADU permits go through LADBS. The city offers an ADU Standard Plan Program that can speed up approvals for certain designs.
• Unincorporated LA County / some cities: ADU permits may go through LA County Planning & Building & Safety using EPIC-LA.

Key ADU Permit Steps

1. Confirm zoning and setbacks (is an ADU allowed on your lot?).
2. Decide on conversion vs detached vs attached unit.
3. Prepare architectural plans and utility layouts.
4. Submit for building, electrical, mechanical, and plumbing permits.
5. Respond to plan check comments and obtain approvals.
6. Schedule and pass inspections up to final sign-off.
